The specs on portland cement says it takes 672 hours to completely cure, it is about 28 days. What effect does that have on air crete? Does it have to sit for that long before you can build with it? It is a 94 lb bag from Lowes. Type l and ll. If not how long before you can start building with it?

It's a bit fragile but hard enough to start working with after 1 or 2 days. It continues to harden over time.
